What is the perimeter in metres of an isosceles triangle with congruent sides measuring 230 cm and the other side measuring 2.9 m?

To calculate the perimeter of an isosceles triangle, you add the lengths of all three sides.

First, we need to convert the measurements to the same units. In this case, we'll convert centimeters to meters because the result is asked in meters.

1 meter is equal to 100 centimeters. So, 230 cm is equal to 230/100 = 2.3 meters.

The triangle has two sides of equal length, so we multiply 2.3 meters by 2, which equals 4.6 meters.

Then, we add the length of the third side, which is 2.9 meters.

So, the perimeter of the triangle is 4.6 meters + 2.9 meters = 7.5 meters.
